Fig. *6 isa longitudinal `section exhibiting the relation and .arrangement of `the different fparts of the machine A`at the moment ofcompletion of the process of -formingior molding.

fllhe rmachine is fconiposed lof the -followingparts which are indicated by the same letters in each Vof the drawings. A, `one Lof the heads of the `machine somewhat similar to Aa lathe-head serving to support the end yof the main shaft J, which carries the flywheel L, and the vfast and loose pulleysiK, K. A, another head serving to support the otherend of the anainshaftand to vcarry `the fbearine's of the pinion `ends of three `shafts C, C, A ,1a third :head in `which are cut three `radial :slots yserving `as guides in which the three shafts C, C, C, move. B, bedplate to which lthe l.three lheads of-the `machine Vare attached. "C,C,C, three shafts to whichare :proach and separate. 4Upon each of these shafts a short dista-nce from the yhead A is xformed Yor turned `a double indlined plane c 6"., surrounding fthe shaft, upon `which the yoke F, and the pinion wheel G,':hereinafter described act. D, D, D, mold wheels Aor `formers rbefore named. rFliese are attached in Vfrontlo'f `.the thead A, ito the extremities of the revolving "shatfts C, C, C,.fby the approximation of which :they :are lbrought to 1act supon rthe portion of metal 'which is to `be molded or formed. The Iform lof rthese wheels Vor foriners which :are so attached as.

Ato be removable at pleasure, `will 'depend upon the `qnartlcu-lar shape `into which it 1s `desired :to A'form the metal Vupon which they not. Fig. @of the annexed drawings repre sents *their form `when the rmachine is `heilig `used Efor the manufacture 'of the ordinary gasoineter rivet; f8, their form when it is used 'for 4the vmanufacture fofia rifie slug, fE, a bar to which =are secured fthe yoke F, and an arm which carries lthe frictionwheel-G. This bar one end of which epesses through :a slot in the head A receives an `alternate motion `backward and forward by the operation of parts'of `the :machine hereinafter described. :F, the `yoke before named.` AItsurrounds the three shafts CQC, C, and is furnished with friction `rollersat its points of Contact with ythemso as to `permit -their free rotation. It fis `provided with `cross-.head,jaws which rest on fguides H H i `along which they slide `or move. As this yoke fis drawn backward in Contact with the Ainclined planes e, c', e', formed on the revolving shafts neXtthe `head A. 'it causes the extremities of these 4shafts which pass through the radial slots in the ihead A, and to which the mold wheels or formers lare attached to approacheachjother. Gr, the friction wheel before named, the la/Xis of which is formed by one `endof the adjustable gagerod P. This wheel when carried forward by the operation of `parts of the machine hereinafter described `acts `uponthe inclined planes `e "e e "formed on the revolving shafts and without interrupting .the `free rotation of the shafts `forces apart :their extremities which pass throughthe radial slots in the head A, so asto permit the disengagement of the portion of the metal which has been subjected to the action of the mold-wheels or formers. This wheel also serves, without interrupting their free rotation to support and steady the revolving shafts C, C, C, while they are subjected to the action of the yoke F-the wheel G receding in contact with the inclined planes e e e as the yoke `F, passes over the inclined planes e e e.

H H, guides before named. J, the main shaft before named. It carries at one end the spur-wheel CZ, which operates on the pinions o, c, c. It also carries the screw WV, which gears into the worm wheel U. The worm wheel U, is provided with a crankpin A77, which at each revolution catches a hook 7L., at one end of the connecting-rod T, and draws the bar E, through the head A, and toward the head A, communicating to the bar and its attachments a backward motion. K, K, fast and loose pulleys before named. L, fly-wheel before named. M, arm fastened at right angles to the bar E, and having attached to its lower end the bar N, which passes through a slot in the head A. This bar in front of the head A is formed into van inclined plane n, which as the bar N, is drawn through the head A with the backward movement of the bar E pushes upward the rod f, upon the upper end of which is placed the cutter wheel y. The cutter wheel g, and rod f, are used when it is necessary to sever or detach the portion of metal which has been subjected to the action of the mold-wheels or formers. O, guide in which the rod f, moves. P, gagerod the adjustment of which determines the length of the portion of metal subjected to the action of the mold wheels or formers. Q, rest for supporting the rod or bar of metal upon the extremity of which the mold wheels or formers aie to act. S, spring surrounding bar E. This spring communicates the forward motion to the bar E, and its attachments and carries the wheel G, along the inclined planes e, e, e, forcing apart the revolving shafts C, C, C. T, connecting rod before named. U, worm-wheel before named carried by a column secured to the bedplate B. W, screw before named keyed to the main-shaft J, and gearing into the worm-wheel U.4

The operation of the machine is as follows: The machine is adjusted as in Fig. 5, for the reception of the metal which is to be molded or formed. If the metal is to be introduced in the form of a bar or rod as in the making of gasometer rivets or slugs, the bar or rod is supported by the rest Q, with its end in contact with the adjustable gagerod P. The power being applied to the pulley K, causes the main shaft J, to revolve, the spur-wheel of which, cl, acts upon the pinions c, c, c, and communicates a rotary motion to the three revolving shafts C, C, C.

The screw W which is keyed to the mainshaft causes the revolution of the wormwheel U, into which it gears, the crank-pin of which p, catches the hook h, of the connecting rod T, and draws the bar E, through the head A', and toward the head A. The bar E, draws with it the yoke F, to which it is attached and which surrounds the three revolving shafts C, C, C, the friction rollers of the yoke heilig in contact with the inclined planes e c e. As the friction rollers of the yoke pass over these inclined planes the ends of the revolving shafts which pass through the radial slots in the head A, are forced to approximate bringing the mold-wheels or formers in contact with the metal which is to be subjected to their action. At the same time the wheel G, which is carried by an arm secured to the bar E, passes in contact with the inclined planes e e e, along which it recedes as the yoke F, encroaches on the inclined planes e e e serving to support and steady the three revolving shafts.

Uien the mold-wheels or formers have attained the greatest proximity to which the machine has been adjusted, the crank pin p, having passed the center of the worin-wheel U, on the side nearest the head A, the hook Iz, of the connecting rod T, becomes disengaged and the bar E, and its attachments are carried by the action of the spring S, back to their original position and the wheel G, passing again along the inclined planes e e e, forces the revolving shafts apart so as to permit the disengagement of the metal which has been molded or formed and the introduction of another portion for the action of the mold-wheels or formers.

If it be desirable to detach or sever from the bar or rod of metal the portion which has been subjected to the action of the moldwheels or formers the cutter-wheel g, mayv be used which is operated as follows: The

arm M, which receives its motion through the bar E, carries with it the bar N, the inclined plane of which n, pushes upward the rod f, with the cutter-wheel g, the parts being so adjusted that the cutter-wheel shall detach or sever the metal at the moment the action of the mold-wheels or formers is completed.

In the manufacture of slugs for fire-arms the cup or cavity in the base of the ball may be formed by giving a conical shape to the end of the gage-rod P, against which the metal is placed.

What I claim as my invention and desire to secure by Letters Patent is l. The revolving shafts C, C, C, with their inclined planes e e', e e, e e, and formed as above described and the moldwheels or formers D, D, D, attached thereto in combination with the yoke F, and wheel G, whereby the extremities Of the shafts to which the mold-Wheels o1' formers portion of metal Which has been molded or are attached are made to approximate and formed may when so desired be severed or separate. detached.

2. I also claim the bar iT, and the inclined CHARLES B. ALLEN. f 5 plane u, in combination with the rod f, and Titnesses at signing: cutter-Wheel g, constructed Lund operated BENJAMIN LOVE, substantially as above described whereby the /VILLIAMS OGLE.
